proved Fountain-Brush, of which thel following is a specification.

This invention relates to brushes or' the like for-wet brushing in which the moistening agent is supplied to the bristles or the like from the body of the brush-(which is made hollow so as to form a liquid reserl voir) through an obturating member adapted to be opened from the exterior.

The invention consists in the arrangement of a force-pump in the body of the brush (which is formed as the reservoir), the cylinder of this pump communicating with the reservoir and being closed on one side by an obturating member and on the other side by theV piston of the pump in such a .manner that when the piston is depressed the obturating member is opened and the moistening agent discharged from the cylinder` under pressureby the actiono'f the piston.

It is advantageous to make the cylinder of.

such a length that it extends entirely through the body of the brush as this 'facilitates obtaining a perfect closure.' Itis also advantageous to arrange the openings establishing communication between the pump-cylinder and the reservoir at such a height above the bottom of the reservoir that even when the brush is reversed with the bristles upward the o enings are still below the liquid level so t at even in this position liquid is able to pass into the cylinder of the pump. By this means the result is attained that in every position of the brush liquid can be discharged by the pump into the bristles and that the reservoir presentsan air-tight closure to the exterior even when the outlet is open. The brush embodying the invention is therefore specially adapted for purposes wherein readily volatile liquids such as benzin or the like are employed as the inoistening agent, such for example as cleaning brushes for typewriters, type and the like and also for purposes where, owing to diiiiculty of access to the object on which the brush is used, it is necessary to use the brush in various positions. X An embodiment of the invention is illustrated by way of example in the accompanying drawing. i

vwhich is made is located above the vl is the body ofthe brush, the handle of hollow so as to form a reservoir. A tube 3 or the like is inserted in the reservoir above the discharge opening 2 and -confnmunicates with the reservoir l through slots 5. An automatically closing valve 6 is' provided for closing the discharge aperture; this valve is opened by exerting pressure on a press-button 47. ln addition to the valve 6 for the aperture 2 there is arranged withinihe cylinder 3 a iston 8,

which' obturates the upper end of t e cylinder and which `when the valve 6 is closed, slots in the piston cylinder i, so that the cylinder is in communication withvthe reservoir. i If the piston is vdepressed for the purpose of moving the valve 6 to a position to open the outlet 2 the slots 5 in the piston cylinder are covered, and the cylinder is cut ofi from the reservoir, so that the reservoir is hermetically closed when the outlet 2 is open. 'llhe piston 8 acts on the liquid that hasentered the piston cylinder in the manner of the piston of a sprayer or syringe and 'sprays the liquid on to the bristles 10, a pad or the like, while on its return movement (and that of the valve (Sinto closing position) it is able to draw in air from the atmosphere, which air passes through the slots 5 (when these are opened by the piston 8) into the reservoir l and replaces the liquid which iiows from the reservoir into the cylinder, thus rendering such dow of liquid possible. For the purpose of hermetically closing the upper-end of the piston-cylinder one or more washers 9" of impermeable material are arranged between the piston 8 and the press-button 7 The reservoir can be filled through a filling `aperture hermetically closed by means of like.

What is claimed is l. A brush for wet brushing, comprising' a liquid reservoir upon force-pump in communication with said reservoir, having a restricted outlet, and adapted to force a column of liquid against its own weight in an inverted position of the brush into said brushing means. v

2.- A brush for wet brushing, comprising brushing means, a liquid reservoir upon said brush, a force-pump adapted to force a column of liquid against its own weight in an inverted position of the brush into said brushing means, said brush, and a a screw plug llorthe ice llU

, said brush,- and a brushing means, said force-pump comprising a piston, a cylinder havinga liquid outlet, and a valve controlling the passage of liquid through said outlet.

3. A brush for wet brushing, comprising brushing means, a liquid reservoir upon said brush, a force-pump adapted to force a column of liquid against its own weight in an inverted position of the brush into said brushing means, said force-pump comprising a vcylinder having a liquid-inlet and a valve controlled outlet, a piston, and a valve controlling the passage of liquld through saidv outlet, said pistonA operating to close saidinlet in the initial part of its pressurestroke. A

4. A brush for wet brushing, comprising brushing means, a liquid reservoir, upon said brush, and a force-pump adapted to force a column of liquid against its ownweight in an inverted position of the brush into said brushing means, said force-pump comprising a piston, a cylinder having a liquid outlet therein and a valve controlling the passage'of liquid through said outlet,-said valve having its movements controlled by said piston.

5. A brush for wet brushing, comprising a brushing means, "a liquid reservoir upon force-pump adapted to force a column of liquid against its `own weight in an inverted position of the brush into said brushing means, said pump comprising a cylinder located in said reservoir,

linto said brushing means,

and a piston in said cylinder, said cylinder vhaving an inlet thereto from said reservoir,

and a valve-controlled liquid outlet.

6. A brush for wet brushing, comprising a brushing means, a liquid reservoir upon said brush, and a force-pump adapted to force a column off liquid against its own Weight in an invertedposition of the brush into said brushing means, said pump comprising a cylinder located in said reservoir, and a piston in said cylinder, said cylinder having an inlet thereto Jfrom said reservoir, and a valve-controlled liquid outlet, said piston operating to close said inlet in the initial part of its pressure stroke and oontrolling the' operations of said outlet valve.

7. A brush for wet brushing, comprising a brushing means, a liquid reservoir upon said brush, and a force-pump adapted to force a column of liquid against its own weight in an inverted position of the brush said pump comprising a cylinder located in said reservoir and passing entirely throu h said reservoir, and a piston in said cylin er, said cylinder having an inlet thereto from said reservoir, and a valve-controlled liquid outlet.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
